Electroplating processingIt is a process that uses electrolysis to process the surface of parts. When electroplating, the parts are cathodes, and the metal ions in the plating solution are deposited on the surface of the parts under the action of direct current to form a uniform and dense metal coating. The necessary condition for plastic electroplating is an electrolysis device composed of an external DC power supply, plating solution, plating parts, and anode.

The purpose of plastic electroplating processing is to achieve various technical properties such as decoration, corrosion resistance, and wear resistance by changing the appearance and physical and chemical properties of the part surface. Functional coatings can also be applied according to specific process requirements, such as weldability, electrical energy, magnetic energy, and photo energy coatings, to fully expand the application range of metal materials.

Electroplating has been widely used in various production and scientific fields of the national economy. Especially in industries such as machine manufacturing, national defense, communication, transportation, and light industry, it has become an indispensable part. Electroplating is widely used in mechanical production to improve the wear and corrosion resistance of various shafts, sleeves, and other components. It plays an increasingly important role in sealing and anti-corrosion of various high-pressure gaskets, as well as repairing dimensions of various mechanical wear and processed parts.

Electroplating is one of the fundamental processes in the manufacturing industry. Due to the unique technological and economic advantages of plastic electroplating processing, it is not only difficult to completely replace, but also constantly makes new breakthroughs in fields such as electronics and steel. After the reform and opening up, the electroplating industry has also entered a period of rapid development, with a large number of foreign manufacturers entering economically developed and convenient transportation areas such as the Yangtze River Delta, Pearl River Delta, and Bohai Rim in China, and their basic process providers, electroplating enterprises, have also flocked in. The application hotspot of electroplating processing has shifted from industries such as machinery and light industry to electronics and steel industries, from simple protective decorative coatings to functional coatings, and from relative dispersion to gradual integration. And the types of electroplating are also constantly increasing, from the earliest gold, silver, and copper plating to later nickel, zinc, hard chromium, and tin plating.
